reasons why real man don't drive electric cars

[Viper GTS]

3. Electric cars suck on acceleration.

Did you research this at all before you crapped it into your keyboard?

Electric cars can be absolute demons on acceleration. Why?

1) They're torquey as hell.
2) They're always at peak power - no gear changes/power curve to worry about. Power and torque curves are flat.

The output power of battery limits any attempt to push a car faster. Last time, someone did a rough estimate: The total energy contained in 1000 pound batteries is as much as 0.9 litre of gasoline.

False.

You'd be surprised how much legitimate scientific research is manipulated, distorted and misrepresented in order to further a person's or group's own interests.

Tell us where you derive your insights from. How can you be sure your source are unmanipulated and on top of that correct in their analysis? Saw it on TV?

 

[SsZERO]

I don't derive insights, I arrive at conclusions based on facts. I do not rely on one source for information, nor do I accept whatever is told at face value without doing research on my own...but you should stick to watching TV for deriving your insights, because it doesn't matter whether you know the truth or not, it's not like you'll make a difference either way.

He was wrong on that one point, but overall he was correct. Electric cars are nothing more than a novelty, far too impractical for mainstream production/use. Their list of disadvantages is even longer than that of early diesel engines.

While I will agree that fully electric vehicles are currently a novelty, hybrid technology has real potential.

What if you used a decent sized 4 cyl to produce electricity, instead of a tiny engine? For example, a 2.2L or something like you'd see in an Accord. If the focus was shifted somewhat off the supreme gas mileage, performance could be quite decent. Hybrids are also not susceptible to the vast majority of the faults he listed, the only exception being the motor sound.

And frankly, who needs motor sound?

How do you know your 'facts' are indeed facts?

That must be the lamest attempt at a flame that I've seen in a long while.

<< That's not to mention that battery powered cars are substantially more INefficient than any IC engine...it just doesn't float. If it did, we'd have seen more electric cars by now >>



The reason why we don't see more battery powered cars is simple - money. Money, money and money. Money makes the world go around, Oil companies have money, people who are at the top have the power - they like to keep it that way. If everybody was using cheap, electric energy, these power-hungry, greedy oil companies wouldn't be making profits now would they?
Isn't anybody curious why this technology is so slow to implement? Don't you think they can make lightbulbs that last decades, or auto tires that last 10x longer? Things are made to last, aren't made to be efficient - we live in a disposable, greedy era. No $$ in electric cars.

Battery only powered cars are not going to do much good with the enegry density of batteries available today. And of course it's only ever going to be as clean as the plant supplying the power.

But hybrids are a totally different story, agreed. If the economy minded hybrids sell well, I think there will be something more performance minded available soon. Could do some neat tricks (traction control, adjustable balance...) with e-engines at each wheel plus a computer. If they could only get down the weight a bit further...

 

[SsZERO]

The setup you speak of is already in use on diesel locomotives...but it is that way for a reason -- it would be more difficult to drive the wheels directly with the diesel engine, so each wheel carriage under the locomotive has 2 electric motors. Using a 4-cyl engine to power an electric motor would be pointless...and with that type of engine only producing 120-140 PEAK HP, the power available for the electric motor will be quite a bit less. It would be a very inefficient configuration, and to make it hi-performance would take even more effort than making a Civic fast.

As for who needs motor sound....that's like saying "Who needs real instruments, sound synthesis is good enough."

Incorrect.

There are ways of determining whether something is a verifiable fact or not. I'm sure someone who asks such prudent questions as you do is aware of these methods...And I did not make any attempt at a flame, I simply stated a fact.

We'll see. I like the sound of a gas-powered engine...but if a electric car can run faster and save me money, then I'll consider it.

But daaaaamn they're ugly. I'm not an enviromentalist in any way at all...so if they want me to help out then they're at least gonna have to engineer a car that isn't hideous.

 

Where do we put all these batteries when we are done with them too?

 

[jeremy806]

Electric cars are just dumb. I think that research should go toward better converters, etc. for regular IC engines.

Didn't you read some of the later posts in this thread? Battery powered electric cars are some of the most inefficient devices ever created it. Think about it...how much power is needed to charge a battery...and now how much power does that battery provide. Electric cars are simply not a solution to anything at this point in time...and it has nothing to do with the interests of the "evil big business" you speak of.

We simply drop them in the ocean, or stack them in the local landfills. OR we can incinerate them, releasing gases that are much more toxic and concentrated than anything released from the exhaust pipes of gas powred cars.

wasn't there a racing electric car built a while ago? i just remember it was fast

it should be possible to make a hybrid for performance, would cost more as more parts but that would be sweeet

Well you're partly correct on the first statement. Electric motors doesn't have anymore torque than engines when accelerating from speed such as passing.

Engines have peak torque when the RPM is about 3,500.

1. Electic motors have the peak torque at zero RPM and rotational speed is pretty much inversely proportional to torque, therefore it will prevail engines when starting from dead stop.

2. I don' think so...

I should have been a little more specific:

1) They produce peak torque at any RPM (I was specifically referring to their low end torque - great for getting off the line)
2) Assuming you don't have it geared (simply use RPM to control speed), AFAIK the HP & torque curves are flat. If you can show me otherwise, I'll stand corrected.

Gregg, take a look at this stuff about motors

1. Torque is inv. prop. to RPM, therefore it can only produce peak torque at stall.

2. This particular motor has parabolic power. RPM curve, curve shape WILL vary depending on type of the motor.


There is also something called relative torque that compares the torque at 100% rated RPM vs. starting torque especially on alternating current induction motors.

And the fact that the petroleum that runs these IC engines is limited just won't be an issue eventually? People have to wake up. We don't have unlimited gasoline reserves and the exhaust isn't so great for the planet in general. Electric cars are a very, very practical concept (which I'll admit isn't quite where it needs to be for broad acceptance but it will be soon). Once they get the # of miles per charge up an electric car then it should be practical for just about anybody who doesn't need insane power and speed to prove something to the world.
